JTS Topology Suite

The JTS Topology Suite is an API of spatial predicates and functions for processing geometry. It has the following design goals:

JTS conforms to the Simple Features Specification for SQL published by the Open GIS Consortium
JTS provides a complete, consistent, robust implementation of fundamental algorithms for processing linear geometry on the 2-dimensional Cartesian plane
JTS is fast enough for production use
JTS is written in 100% pure Java^TM

JTS provides spatial analysis methods such as Intersection

Software

JTS versions can be downloaded from the SourceForge JTS site.

Support

The JTS Mailing List is a forum to discuss all aspects of the JTS Topology Suite. Algorithm design, implementation issues, application issues, bug reports, etc, are all discussed on this list.
